The BBD 12DS is the silenced version of Atlas Copco's BBD 12D, built for the same horizontal and plug-hole drilling work but with a polyurethane cover designed to cut noise levels by up to 50%. It's suited to sites where operator noise exposure needs closer control — urban construction, confined work areas, or any job where prolonged drill noise is a concern.
Like the standard BBD 12D, the BBD 12DS (8311 0102 80) uses a D-type handle for horizontal drilling, plug hole drilling, and drilling in concrete, working to a shallow depth of around 1 metre.
At roughly 10.7 kg, it's slightly heavier than the standard BBD 12D — the silencer housing adds a bit of mass — with air consumption around 22 l/s and an impact rate of about 2,580 blows per minute.
Unlike the BBD 12D, which RMT offers as both an original Atlas Copco tool and the RMT 12D aftermarket equivalent, the BBD 12DS is available through RMT only as the genuine, original Atlas Copco tool.
There is currently no RMT-manufactured aftermarket version of this specific silenced model. It comes in a single shank size — Hex 19 x 108 mm (8311010280), so there's no shank selection to make; buyers simply need to confirm this matches their existing drill steel.
If your site has adopted stricter noise controls, or your operators are raising concern about extended exposure to standard drill noise, the BBD 12DS is worth checking against your current setup.
The silenced design makes it a suitable option for applications where operator comfort and noise reduction are important along with reliable drilling performance.
